Embodiment
Fig. 1,2 and 3 shows respectively exemplary imaging system, that is, the front elevation of illustrative gamma camera 10, side view and vertical view, this gamma camera 10 has two detecting heads 12,14, and each detecting head includes radiation- sensitive face 16,18 separately.The gamma camera 10 of two statures is illustrative example, should be appreciated that disclosed herein for shipment easily and re-assembly at destination locations other imaging system that the apparatus and method of imaging system can be applied to gamma camera, CT/SPECT system, PET/SPECT system and comprise the detecting head being arranged in mechanical framework.And, disclosed herein for shipment easily and in the apparatus and method that destination locations re-assemblies imaging system, can be applied to there are two detecting heads, gamma camera or other imaging system of three detecting heads, four detecting heads or more detecting heads.
Detecting head 12,14 is arranged on framework 20, and this framework 20 comprises for mechanically operating the operating means 22,24 of each detecting head 12,14.In the exemplary embodiment, framework 20 limits chamber, and patient can move through this chamber in prone position.When the operational configurations shown in Fig. 1-3, operating means 22,24 coordinate detection heads, make their radiation-sensitive face separately 16,18 in the face of object that will imaging.When the operational configurations shown in Fig. 1-3, radiation- sensitive face 16,18 observation central examination region 30.Such position is for example suitable for lying in the tomography of the patient on bench, sick bed or the saddle (not shown) in the inspection area 30 between radiation-sensitive face 16,18.When other operational configurations, can use other orientation of detecting head 12,14.For example, Fig. 1 shows with the virtual image patient that another possible 14a，Gai position, position 14a of detecting head 14 is suitable for from standing or being seated and obtains planar imaging data.The operating means 22,24 of example comprises detector rotary shell or assembly 32,34 separately.For example, detector rotary shell or assembly 32,34 make detecting head 14 rotate in Fig. 1 the position 14a with virtual image example.Comprise that the extra operation degree of freedom that the operating means 22,24 of example and the mechanical framework 20 of other mechanism provide makes detecting head 12,14 (optimal visibility and sign in the front elevation of Fig. 1) rotation around chamber along circular frame path 36.
Typically, operation degree of freedom does not comprise leaning device or other degree of freedom that can make extremely more parallel with the principal plane 40 (draw and mark) of framework 20 position of head tilts in the side view of Fig. 2.On the contrary, when gamma camera 10 is during in operational configurations shown in Fig. 1-3, the radiation- sensitive face 16,18 of detecting head 12,14 is arranged to cross principal plane 40 conventionally.Therefore, detecting head 12,14 is outwards relatively outstanding away from the main body of framework 20.Although this layout is favourable to imaging, unfavorable for shipment, because it causes along the relatively large size d of the outstanding direction gamma camera 10 of detecting head 12,14
op.Size d
opbe greater than the width of typical 36 inches (90cm) of typical European hospital entrance, and be greater than the width of typical 40 inches (100cm) of typical United States Hospital entrance.
Referring now to Fig. 4-6, obsolete at least one extra degree of freedom when the framework 20 of gamma camera 10 is included in imaging, but this at least one extra degree of freedom is for being configured to compacter shipment kenel by gamma camera 10, in this shipment kenel, the size reduction of gamma camera 10 is to the less value d shown in Fig. 5 and 6
ship.This is by providing or pivot joint 41,42 (with folding or shipment kenel signs in non-folding or operational configurations and Fig. 4 and 6 in Fig. 2) and realizing, tilt or pivot joint 41,42 make detecting head 12,14 can pivotable or folding, the principal plane 40 that makes radiation- sensitive face 16,18 be parallel to framework 20 is arranged, and is faced the principal plane 40 of framework 20.In the exemplary embodiment, with operation detecting head rotary freedom with by operating means 22,24 detector rotary shell 32, detecting head 12 is carried out in the 34 operation rotary freedoms that provide 36 cooperations, 14 fold, to be arranged on detecting head 12,14 on top and bottom and the rotated detection head 12 of framework 20,14, make can not collide when framework 20 is folding when them.In the exemplary embodiment, by obsolete each translation mechanism 43 when the imaging, 44 (the folding or shipment kenel signs in non-folding or operational configurations and Fig. 4 in Fig. 1) provide extra degree of freedom, so that folding detecting head 12,14 is the top and bottom of framework 20 centering roughly.
Continuation is with reference to Fig. 4-6 and with further reference to Fig. 7, and gamma camera 10 is manufactured position 52 assemblings 50 in factory or other at first, and is manufacturing position 52 or testing 54 at another mechanism for testing as shown in the figure.Assembling 50 comprises on the operating means 22,24 that mechanically detecting head 10,12 is arranged on to framework 20, and detecting head 12,14 is electrically connected to the operating means of framework 20.After test 54, gamma camera 10 is not disassembled, but uses the framework 20 that comprises operating means 22,24 to make gamma camera 10 folding 56.Folding full automation alternatively and completing by automatic control completely, or comprise alternatively some manual operations, such as taking off clamping screw etc., along the detecting head of pivot joint 41,42 releases such as hand foldable such as grade.Folding detecting head 12,14 passes through friction suitably, or remains on folding position by latch, restraint strap, clamping screw or other securing member etc.In certain embodiments, the folded configuration of detecting head 12,14 in Fig. 4-6 keeps being electrically connected to.In other embodiments, partially or even wholly electricity disconnection of detecting head 12,14.
As used in this, if detecting head 12,14 keeps being electrically connected to substantially, even if the fraction being electrically connected to when gamma camera 10 arranges with folded configuration is disconnected, detecting head 12,14 is also considered to keep being electrically connected to.For example, should imagine and keep detecting head 12,14 to be electrically connected to, but disconnect one or several, connect, for example, the electric terminals of protection is connected in the specific voltage sensitive terminals of detecting head 12,14, or disconnect leader cable so that shipment etc.If break several connections in folding or shipment kenel, the connection of these disconnections coordinates alternatively by connector shape, keying groove etc., to guarantee that these electrical connections can rebuild in destination in free from error mode.
Continuation is with reference to Fig. 4-7, for example, once gamma camera 10, with folded configuration setting, is packed 58 around the gamma camera 10 of folded configuration by using as illustrated with the virtual image wrappage 60 that illustrate in Fig. 4-6 substantially suitably.In folding, from factory or other, manufacture position 52 shipment 64Zhi hospital, laboratory or other destination locations 66 subsequently with the gamma camera of packing kenel.At destination locations 66, gamma camera 10 is arranged in the room, destination of delivery operation 70, and it can comprise the entrance that passes the entrance of 40 inches of width (the Ru U.S. is typical) or pass 36 inches of (90cm) width (as being typical in Europe) in the gamma camera 10 of folding and packing kenel.The folded configuration of gamma camera 10 makes size d
shipenough little of to pass through this entrance.Should imagine for the gamma camera of intending in U.S.'s shipment and have for example width of 38 inches (96cm), it is enough to by typical United States Hospital entrance.If further should imagine destination locations 66, there is suitable more gate, size d
shipshould be greater than 40 inches.
Once be delivered to room, ，Gai destination, room, destination, will operate therein the room of gamma camera 10 typically, knocked-down packing material 60 in taking packaging operation 72 apart.In certain embodiments, delivery operation 70 with take packaging operation 72 apart and can exchange, that is, in gamma camera 10 shipment 70 in folded configuration to before room, destination, can be in hospital's discharging storehouse or other perimeter of destination locations 66 knocked-down packing completely or partially.If door, corridor or other modular building structure in leading to way, room, destination can produce and the closely cooperating of the size of the increase of wrappage 60, can do like this, for example, to make size d
shipminimize.In other cases, ideally wrappage are held in place until system arrives room, destination, so that protection system during through building structure.Once gamma camera 10 is positioned at room, destination and has dismantled wrappage 60, gamma camera 10 is unfolded 74, to be converted to operational configurations from shipment kenel.Alternatively, for clinical, research or other application before, the gamma camera 10 at destination locations 66 in operational configurations is tested 76 again.In certain embodiments, test, adjustment or demarcation in destination can be omitted, replace, rely on accurate test, adjustment or the demarcation of factory or other manufacture position 52, follow to use to fold in shipment, to keep kenel test, adjustment or that demarcate.
With reference to Fig. 8, described the example of an exemplary detecting head fold mechanism.The detecting head 80 with radiation-sensitive face 81 is mounted to detector rotary shell or assembly 84 via arm 82.Tilt actuators 86 is at operation range of tilt angles ΔΦ automatically
opon provide machine to drive operation inclination degree of freedom.In this embodiment, operation inclination degree of freedom is not optimum for folding, at least because it makes arm 82 stretch out from frame.In addition, in certain embodiments, operation inclination degree of freedom can provide the tilt capability that is less than 90 °.Therefore, in order to provide extra degree of freedom by detecting head 80 following folding.When operational configurations, arm 82 is locked in place with respect to detector rotary shell 84 by the decentralizing device 92 of four securing members 90 and two meticulous adjustings.For gamma camera being arranged to folding or shipment kenel, take off securing member 90 and decentralizing device 92, and make detecting head 80 around shoulder bolt 94 from 0 ° of operating position shown in Fig. 8 manually pivotable or rotation to folding position, in folding position, arm 82, generally along 90 ° of orientation shown in Fig. 2, makes radiation-sensitive face 81 in the face of frame.At some embodiment, arm 82 can pivotable be less than 90 °.At some embodiment, when framework 20 allows, arm 82 can pivotable be greater than 90 °, and can partly move in the chamber of framework 20, further to reduce width.One or more securing members 90 or decentralizing device 92 are reinstalled alternatively, to detecting head 80 is locked in to folding position in shipment, and reduce the possibility that securing member 90 or decentralizing device 92 may be lost in shipment.
With reference to Fig. 9, described the example of another exemplary detecting head fold mechanism.The detecting head 100 with radiation-sensitive face 101 is installed on arm 102 rigidly via securing member 103, and arm 102 is mounted to again detector rotary shell or assembly 104 by inclination or pivotable connection 105.Automatically tilt actuators 106 provides around tilting or the machine of pivot joint 105 drives operation inclination degree of freedom, but is only substantially being less than the whole ± operation range of tilt angles ΔΦ of 90 °
opin.For folding detecting head 100 is near frame, one or two bolt or other securing member 110,112 are removed, to completely or partially take off tilt actuators 106.Along with tilt actuators 106 is removed, detecting head 100 and the arm 102 that is rigidly connected can be freely around tilting or pivot joint 105 is switched to 90 ° of positions for loading and transporting of sign downwards.In other words, by taking off securing member 110,112 and wing drop actuator 106, pivot joint 105 is from across being limited angular interval ΔΦ
opoperation degree of freedom be converted to arm 102 rotations that allow detecting head 100 and be attached thereto or the extra degree of freedom that is folded into shipment kenel.
Fig. 8 and 9 fold mechanism are applicable to being included on the framework 20 and actuator 22,24 of gamma camera 10 of Fig. 1-6, so that substantially towards folding each detecting head 12,14 of framework 20, thereby reduce outstanding away from framework of detecting head.In this replacement, Fig. 8 and 9 detecting head 80 or detecting head 100 and the mechanical organ being attached thereto substitute one or two detecting head 10,12 and the element of the actuator 22,24 selected.And, the example based on these examples, those skilled in the art can easily design and be suitable for substantially towards framework, folding the detecting head of other gamma camera with other outstanding physical construction of minimizing detecting head.
With reference to Figure 10-15, described another embodiment.Imaging system 200 is similar with gamma camera 10, but comprise extraly x ray system and radiation monitor, x ray system comprises the radioactive source such as x ray tube 200, x ray system and such as the radiation monitor of x ray detector array 202 via each arm 204,206 are arranged in frame 20, also there is for SPECT the detecting head 12,14 of PET etc.The x ray of inspection area 30 is passed through in 200 transmittings of x ray tube, and is weakened by the object being arranged in this region.The x ray being weakened is surveyed by x ray detector array 202.Therefore, x ray detector array 202 is detecting heads; Yet because of for providing alignment by x ray tube 200 to the path of detector element, x ray detector array 202 does not typically comprise collimator, although it can comprise anti-scatter-grid or other receiving angle limiting structure.And x ray detector array 202 is otherwise different from detecting head 12,14, for example, is designed to receive with the low level ray being detected by detecting head 12,14 typical cases and compares substantially higher x ray stream.Typically, detecting head 12,14 is with the operation of photon or particle counting pattern, and wherein each gamma ray, Alpha or beta particle or other radion are at itself and detecting head 12,14 radiation- sensitive face 16,18 produces discrete corresponding current impulse or other signal while interacting.X ray detector array 202 can count mode or with continuous-mode operation, the latter's generation current or other signal, and the intensity of this electric current or other signal or scale show the rank of the x ray stream of the basic continous colliding on detector element.
X ray system 200,202 can be for static schema, and in this pattern, it is fixing that the azimuth position of x ray tube 200 and x ray detector array 202 keeps, for example, to obtain plane x ray image, plane thoracic cavity x ray.Additionally or alternatively, x ray system 200,202 can be for chromatography pattern, in this pattern, the azimuth position of x ray tube 200 and x ray detector array synchronously increases, to obtain the chromatography data for projection on azimuth coverage, these data can be reconfigured to fragment or 3-D view.In certain embodiments, x ray system 200,202, for obtaining the information about object, obtains decay collection of illustrative plates from this information, the image of this collection of illustrative plates for revising or adjust the SPECT that obtained by detecting head 12,14 or PET imaging data or rebuilding.In certain embodiments, x ray system 200,202 is used as and the SPECT being provided by detecting head 12,14 and/or PET imaging additional replenishment imaging form together.
Figure 10,11 and 12 shows respectively front elevation, side view and the vertical view of the imaging system 190 in operational configurations.Such as detecting head 12,14, identical with the element of gamma camera 10 for operating the gamma camera components of operating means 22,24 grades of each detecting head 12,14, and therefore with the identical reference numerals with using in Fig. 1-3.Imaging system 190 comprises the x ray tube 200 being arranged on arm 204 in addition, and arm 204 extends away from framework 20 conventionally.Similarly, x ray detector array 202 is arranged on arm 206, and arm 206 extends away from framework 20 conventionally.In operational configurations, x ray tube 200 is arranged on the opposite side of inspection area 30 in the mode facing with each other with x ray detector array 202.The x ray being produced by x ray tube 200 is by inspection area 30, in this inspection area, the x radiation absorption of x ray based on object (conventionally changing spatially) characteristic and weakening, and the x ray detector array 202 being positioned on opposite side receives and detects by the intensity of the x ray that absorption weakens substantially of inspection area 30.
In exemplary imaging system 190, along the size d of the imaging system 190 of detecting head 12,14 projected directions
opbe subject to the restriction of the extension of detecting head 12,14, and x ray system element 200,202 is extended or outstanding shorter distance in this direction.Yet, in other embodiments, can limit the outstanding of x ray system element.Yet, even in the exemplary embodiment, x ray system element 200,202 outstanding enough large, to stop the imaging system 190 of operational configurations to pass through hospital's entrance, for example, at the entrance of typical 40 inches of width of the U.S., at the entrance of 36 inches of (90cm) width in Europe, or both.
Figure 13,14 and 15 shows respectively front elevation, side view and the vertical view of the imaging system in folding or shipment kenel 190 '.Detecting head 12,14 in as Fig. 4,5 and 6 example for the identical folding position of gamma camera 10.In addition, x ray components 200,202 is folding near framework 20.In folded configuration 190 ', x ray tube 200 rotates up around pivot joint 210 substantially, and the length of operating means 204 shortens alternatively via telescopic mechanism, sliding sleeve joint 212 or other suitable hookup.Similarly, in folded configuration 190 ', x ray detector array 202 rotates up around pivot joint 220 substantially, and the length of operating means 206 shortens alternatively via telescopic mechanism, sliding sleeve joint 222 or other suitable hookup.Imaging system 190 in shipment kenel 190 ' be suitable for for example with Figure 13-15 in virtual image diagram wrappage 160 packings that illustrate, and according to illustrating the method shipment illustrating in Fig. 7.
